Let me explain:
I have no inside knowledge, but I'm guessing that IBM has started to build a platform first (API first). That - and the option of adding Watson services - looks promising (I'm a developer - YMMV). But I did not have the time to start playing with the API, yet. So not enough of experience to start talking about that either.

For an end user the current version lacks too many features to be usable/comparable to other products. But it's a preview/alpha sort of thing, so I'm waiting for IBM Connect to decide on that.
